Abstract Microscopical observation was made during and after intensiostatic polarization of Armco iron electrodes. A correlation between etching degree and grain orientation was evident in sulfuric acid solutions. In hydrochloric acid solutions a smoothing at the inside of the grains, independently of their orientation and preferential corrosion at the boundaries occurred. It is suggested that in sulfuric acid the dissolution mechanism involving anion participation may be effective, while in hydrochloric solutions a competitive adsorption very probably takes place between Cl− and OH− or water molecules.

The erosion hindrance of carbon steel in 1M HCl in nearness and nonappearance of terminated Hydrocortisone Sodium Succinate has been examined utilizing mass-loss. Comes about gotten appeared that the restraint productivity expanded with the increment of the concentration of the utilized medicate and diminished with the increment of temperature. The adsorption of this sedate on carbon steel surface takes after Langmuir’s adsorption isotherm. A few thermodynamic parameters were calculated. The motor parameters of erosion of carbon steel in HCl arrangement have been examined. Keywords: Corrosion inhibition; Carbon steel; Hydrocortisone
